IT IS disgraceful that in this day and age holiday-makers are still being sent to foreign resorts to die of carbon monoxide poisoning.

As far back as 1959, two children were orphaned when their parents met their fate at a motel in Portugal.

The local “experts” put their deaths down to food poisoning from the clams which they had eaten, despite the fact that none of the other people who had eaten clams had the slightest symptoms.

Home Office Pathologist Prof Keith Simpson proved otherwise.

There has been a television documentary featuring other cases and yet this is still going on. This type of water heater should have been banned years ago and all travel agents should be aware of it and stop sending people to such places.
